117P Immune checkpoint inhibitors (ICI) in combination with chemotherapy as first-line (1L) treatment for non-small cell lung cancer (NSCLC): A pair-wise meta-analysis (MA)
ConclusionThe association of immunotherapy plus CH is a better treatment option for all patients in 1L NSCLC. Standard subgroups are the most benefited, except liver mx patients and EGFR/ALK+ especially benefited for the combination of an antiPD-L1 and an antiVEGF.

56P Predictive factors of intensive care outcomes of patients admitted with immune-related adverse events
ConclusionIt is likely that the number of critical care admissions may increase with more patients receiving ICPI. These events can be responsible for great morbidity which might be associated with increased mortality. IB such as high LDH, high NLR and high SIRI might correlate to poor outcome and worse survival and could be used to develop awareness of these events and a more effective approach. However, some of these results were not statistically significant and further studies are needed with a larger data to validate them.Legal entity responsible for the studyThe authors.FundingHas not received any funding.DisclosureA...

7P Multispectral immunofluorescence and computational imaging analysis define the prognostic role of T-cell infiltrates in gastric cancer
ConclusionThis study identified and validated CD45RO and FOXP3 T cell infiltrates as independent prognostic markers in Western GC patients. This may enable personalized follow up or (neo)adjuvant treatment strategies. Whether high infiltrates are predictive of immunotherapy benefit should be assessed. Unexpectedly, high FOXP3 densities were associated with longer CSS, warranting studies into the role regulatory T cells in GC.Legal entity responsible for the studyMarco Gerlinger.FundingNational Institute for Health Research and Biomedical Research Council - Royal Marsden Hospital, Cancer Research UK, Schottlander Foundation...

8P The prognostic value of tumour-infiltrating lymphocytes (TILs) in pancreatic cancer: A systematic review and meta-analysis
ConclusionHigh infiltration of CD3+ and CD8+ lymphocytes is associated with improved OS among patients with resected PC, whereas high infiltration of FoxP3+ T cells is associated with decreased OS. CD4+ and CD20+ lymphocytes did not have a significant impact on OS. Based on these findings, staining for TILs, especially CD3+, CD8+ and FoxP3+ T cells, might be an important tool for future assessment of patient survival and prognosis, as well as for tailored oncological therapy.Clinical trial identificationCRD42019134744.Legal entity responsible for the studyThe authors.FundingCenter for Surgical Science.DisclosureAll authors...
